CENTRIFUGAL CLOTHES-DRIER.

Specification of Letters Patent.

Application filed April 6, 1910.

Patented Sept. 13, .1910.

Serial No. 553,686.

To all whom it may concern:

Be it known that I, FRANK A. DrNsMonn, a citizen of the United States,residing at Fredonia in the county of Chautauqua and State of New York,have invented a new and useful Centrifugal Clothes-Drier, of which thefollowing is a specification.

This invention relates to centrifugal clothes driers and is moreparticularly designed as an improvement upon the structure disclosed inPatent No. 915,921, issued to me on January 11, 1910. In devices of thischaracter such as heretofore devised it has been difficult to hold thewet fabrics properly centered within the rotating receptacle because,unless the weight of the fabrics is accurately equalized upon the bottomof the receptacle, the said fabrics will be thrown off center as thereceptacle rotates at a high speed and considerable vibration of themachine will thus be produced.

One of the objects of the present invention is to provide simple meanswhereby the fabrics can be held against shifting off center within thereceptacle and vibration of the machine is thus eliminated.

With this and other objects in view the invention consists of certainnovel details of construction and combinations of parts hereinafter morefully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings :Figure 1 is a vertical section through a clothes drierhaving the present improvements embodied therein. Fig. 2 is a horizontalsection through the receptacle or fabric holding basket of the machineand showing the corrugated bottom thereof. Fig. 3 is a bottom plan viewof the holding disk.

Referring to the figures by characters of reference 1 designatessupports connected adjacent their lower ends by one or more cross strips2 and additional cross strips 3 connect the said supports at pointsabove the strip 2. The receiver 4 is fixedly mounted between thesupports 1 and above the strips 3 and has an outlet 5 extending from thebottom thereof.

A shaft 6 is mounted upon the strips 2 and 3 and extends through thecenter of the receiver 41-. This shaft has an enlargement T thereonwithin the receiver and to which is secured the bottom 8 of afrusto-conical basket 5). Said bottom is formed with concentric circularcorrugations such as have been indicated at 10, said corrugations beingalso concentric with the center of the basket and being prefc ablyarranged with their uppermost portions in the same plane. The upper endof the basket is open and the shaft (3 extends a short distancethereabove. Apcrturcs 11 are formed within the wall of the basket andclose to the corrugated bot tom 8 l'llQl'OOf, these apertures beingarranged bclow the level of the upper end of the receiver -'.l-.

A holding disk 12 is removably mounted upon the shaft (5 and within thebasket 5), this disk being provided with an upstanding central boss 13into which projects a set screw 14 adapted to bind upon the shaft andhold the disk fixed relative thereto. The said disk is formed with aplurality of concentric corrugations such as have been ind' :ated at 15.The shaft 6 may be operated in any suitable manner, as by means of acord or belt 16 extending partly around a pulley 17 secured to theshaft, opposed stretches of the said cord or belt being mounted oninclined sheaves 18 and the said belt extending over a drive wheel 1!)which may be provided with a handle 20.

In using the machine herein described the disk 12 is removed from shaft6 and the wet fabrics to be dried are placed within the basket 9 anddistributed as evenly as possible around the shaft 6. The disk 12 isthen placed on the upper end portion of the shaft and pushed downwardthereon until its corrugations tightly engage the fabrics. The disk canthen be locked by means of the set screw 14. It will thus be seen thatthe body of fabrics will be firmly clamped between two surfaces each ofwhich has concentric corrugations and it has been found by actualpractice that, when the basket is rapidly rotated, the said corrugationswill operate to maintain the fabrics properly centered throughout theoperation and the machine will not at any time lose its proper balanceand vibrate to an objectionable extent.

It is to be understood of course that various changes may be made in theconstruction and ar 'angement of the parts without departing from thespirit or sacrificing any of the advantages of the invention as definedin the appended claims.

What is claimed is l. A centrifugal clothes drier including an aperturedbasket having concentric corrugations on the bottom thereof the upperportions of which are disposed in the same plane, and means revolubleWith the basket for holding fabrics upon said bottom.

2. A centrifugal clothes drier including a revoluble basket havingapertures in the Wall thereof, the bottom of said basket havingconcentric annular corrugations the upper portions of Which are locatedin the same plane, and means adjustably and re movably mounted in thebasket for holding fabrics upon said bottom.

3. A centrifugal clothes drier including an apertured basket mounted forrotation, and means adjustably mounted Within the basket for holdingfabrics upon the bottom of said basket, said means including concentricannular corrugations.

4. A centrifugal clothes drier including a revoluble apertured basket,and means removably and adjustably mounted Within the basket for holdingfabrics upon the bottom of the basket, said means including concentricannular corrugations for engaging the fabrics.

5. A centrifugal clothes drier including an apertured basket mounted forrotation, said basket having concentric corrugations on the bottomthereof, and means adjustably mounted Within the basket for holdingfabrics upon said corrugations, sald means 1ncludingconcentriccorrugations for engaging the fabrics.

6. A centrifugal clothes drier including a basket mounted for rotation,said basket having concentric corrugations upon the bottom thereof, acentral shaft revoluble With the basket, and a fabric holding deviceadjustably mounted on the shaft and having concentric fabric engagingcorrugations.

7. A centrifugal clothes drier including a basket mounted for rotation,a shaft extending through and revoluble With the basket, said baskethaving concentric corrugations upon the bottom thereof, and a diskadjustably and removably mounted upon the shaft and having concentricfabric engaging corrugations.

8. A centrifugal clothes drier including a basket mounted for rotation,said basket having concentric corrugations on the bottom thereof, ashaft extending concentrically Within and revoluble with the basket, adisk adjustably mounted on the shaft and having concentric fabricengaging corrugations, and means for securing the disk to the shaft.

In testimony that I claim the foregoing as my oWn, I have hereto affixedmy signature in the presence of tWo Witnesses.
